WILLIAM J. THU'L, MELROSIEl, MINNESOTA.

AUTOMOBILE-neutrons mrrirssn Am: narmcron.

To all whom it may concern:

Be it known that WILLIAM J. THUL, a citizen of the United States, and resident of Melrose, in the county of Stearns and State of Minnesota, has invented certain new and useful Improvement in Automobile-Head- Light Difl'use'rs and Deflectors, of which the following is a specification.

This invention'relates to automobile headlight difl'users and deflectors, and one of the principal objects of the invention is to provide, reliable and eflicient means for preventing the glare of the light from blinding the sight of pedestrians.

Another object of the invention is to provide a head-light difiuser for automobiles in which the light is deflected downward without changing the construction or operation of the light or the reflector.

Still another object of the invention is to provide a headlight deflector, preferably of flexible semitransparent .material such as celluloid, ground on one side, and which is adapted to be fitted'over the glass opening of I the head-light.

These and other objects may be obtained in the accompanying drawin in which,

Figure 1 is a front view 0 an automobile headlight with the diffuser attached thereto.

Fig. 2 is an end view of the diffuser.

Like reference characters represent like parts throughout the several views.

Referring to the drawing, the numeral? denotes the outermost portion of the headlight reflector and which contains a number of fastening pins 4. It will be readily understood that this reflector is concave and tends to project the light rays directly forward, thereby making it diflicult for the operators of approaching vehicles to see the oncoming vehicle or the roadway over which they are traveling. To obviate this intense glare from the head-light reflector and incidentally to deflect a suflicient portion of the light rays in a downward direction so that the roadway may be more clearly distinguished, I provide a celluloid disk 5 having a number of notches 6 on its edge, the disk being adapted to lie flat against the glass pane of the head-light, the sins 4. fitting into the notches 6, thereby hol ing same against ordinary removal. The disk 5 mayv ,loid disk Specification of Letters Patent. Patented Dec, 18, 191 '1, Application filed November 5, 1915. Serial No. 59,875.

also 'be made slightly larger than the inner and the reflector ring 3 as shown by the dotted lines.

The disk 5 is ground on one side as indicated by the numeral 7. This has the eifect of difl'using the light rays as projected from the reflector and eliminates the glare. In order to deflect some of the light rays where they are most needed, namely in a downward direction in order to illuminate the road-way, immediately inv front of the vehicle, I rovidea series of vanes 8 as shown.

As Wlll be readily apparent, these vanes are sim ly pressed outward at an angle from the dis so that that portion of the light which would otherwise be reflected backward from the disk, the ground portion 7 acting also as a partial reflector, is now uti-,

lized in a "cry effective manner without ma terially affecting the volume of light diffused by the apparatus.

From the foregoing it will be obvious that while it will afford to the head-light a neat and elegant appearance.

Various changes may be made in the details of construction without departing from the'spirit and scope of the inventionasdefined in the claims. What is claimed is 1. A headlight dimmer comprising a -'cellu-.

loiddisk ground on the outside so; tha t; the

disk is light diffusing, and a series of angu. larly disposed vanes, each vane formediby cutting the disk transversely in a horizontal line and pressing this part outwardly, and

so spaced from the adjacent vanes that a flat, 'difi'using and reflecting rtion is interposed between each pair 0 vanes of the series.

2. A headlight dimmer comprising a celluound on the outside so that the disk is lig t diffusing, and a series of angularly disposed vanes, each vane formed by cutting the disk transversely in a horizontal of Stearns and.
